Machine Learning for Prediction of Non-Small Cell Lung Cancer Based on Inflammatory and Nutritional Indicators in Adults: A Cross-Sectional Study.

Purpose: The aim of this study was to evaluate the potential benefit of blood inflammation in the diagnosis of non-small cell lung cancer (NSCLC) and propose a machine-learning-based method to predict NSCLC in asymptomatic adults. Patients and Methods: A cross-sectional study was evaluated using medical records of 139 patients with non-small cell lung cancer and physical examination data from May 2022 to May 2023 of 198 healthy controls. The NSCLC cohort comprised 128 cases of adenocarcinoma, 3 cases of squamous cell carcinoma, and 8 cases of other NSCLC subtypes. The correlation between inflammatory and nutritional markers, such as monocytes, neutrophils, LMR, NLR, PLR, PHR and non-small cell lung cancer was examined. Features were selected using Python's feature selection library and analyzed by five algorithms. The predictive ability of the model for non-small cell lung cancer diagnosis was assessed by precision, accuracy, recall, F1 score, and area under the curve (AUC). Results: The results showed that the top 14 important factors were PDW, age, TP, RBC, HGB, LYM, LYM%, RDW, PLR, LMR, PHR, MONO, MONO%, gender. Additionally, the naive Bayes (NB) algorithm demonstrated the highest overall performance in predicting adult NSCLC among the five machine learning algorithms, achieving an accuracy of 0.87, a macro average F1 score of 0.85, a weighted average F1 score of 0.87, and an AUC of 0.84. Conclusion: In feature ranking, platelet distribution width was the most important feature, and the NB algorithm performed best in predicting adult NSCLC diagnosis.

A Comparative Study of National Family Health Survey-4 and National Family Health Survey-5 of Nutritional Indicators in Chhattisgarh.

Globally, public health issues related to malnutrition exist. One of the countries grappling with challenges in combating anemia and malnutrition is India, including the state of Chhattisgarh. The National Family Health Survey-5 (NFHS-5) data show that the advancements made in the National Family Health Survey-4 (NFHS-4) were reversed in NFHS-5. Despite having several programs and policies in place, Chhattisgarh has not yet utilized all of its potential to demonstrate exponential reductions in anemia and malnutrition. This study highlights probable factors and inter-district variations to provide an overview of the nutritional condition of districts in Chhattisgarh compared to NFHS-4. Children under five who are severely wasted, stunted, or experiencing both conditions exhibit a lower prevalence. An immediate warning indication was the rise in anemia prevalence across all age categories. In Chhattisgarh, when comparing NFHS-5 to NFHS-4, the study identified a reduced frequency of direct determinants and an increased coverage of nutrition-specific treatments. The state of Chhattisgarh has seen a significant improvement in underlying factors, including the number of homes with power and drinking water quality. It also describes the shortcomings and advancements in the inter-district variations among the coverage factors. Instead of focusing on raising the nutritional indicators for Chhattisgarh, this study also includes initiatives made by states that have fared better in terms of those metrics.

A novel nomogram based on body composition and nutritional indicators to predict the prognosis of patients with muscle-invasive bladder cancer undergoing radical cystectomy.

OBJECTIVE: To investigate the prognostic significance of body composition and nutritional indicators in patients undergoing radical cystectomy with muscle-invasive bladder cancer (MIBC) and to develop a novel nomogram that accurately predicts overall survival (OS). METHODS: From December 2010 to December 2020, we retrospectively collected clinical and pathological data from 373 MIBC patients who underwent radical cystectomy at our hospital. Preoperative computed tomography (CT) images were used to measure the skeletal muscle index (SMI), subcutaneous adipose index (SAI), visceral adipose index (VAI), skeletal muscle density (SMD), subcutaneous adipose density (SAD), visceral adipose density (VAD), and visceral adipose to subcutaneous adipose area ratio (VSR). The clinicopathological characteristics were evaluated using LASSO regression and multivariate Cox regression, and a nomogram was constructed to predict 1-, 3-, and 5-year overall survival. The concordance index (C-index), time-dependent receiver operating characteristic curves (t-ROC), calibration curve, and decision curve analysis (DCA) were used to assess the discriminative ability, calibration, and clinical practicality of the nomogram. RESULTS: Multivariate analyses demonstrated that pT stage, lymph node status, LVI, SMD, and prognostic nutritional index (PNI) are independent prognostic factors for OS. Additionally, a nomogram was created. The nomogram's C-index was 0.714 (95% CI: 0.695-0.733). The area under the t-ROC curve of 1-, 3-, and 5-year survival corresponding to the model was 0.726, 0.788, and 0.785, respectively. The calibration curve demonstrated excellent agreement between the predicted and observed outcomes. The DCA revealed that patients with MIBC could benefit from the nomogram. CONCLUSION: Based on body composition and nutritional indicators, we developed a novel nomogram with excellent predictive accuracy and reliability for predicting the prognosis of MIBC patients undergoing RC.

A large-scale study integrating nutritional indicators and clinicopathological parameters to evaluate prognosis, follow-up, and postoperative chemotherapy decisions in rectal cancer patients.

OBJECTIVE: The aim of this study was to evaluate the role of nutritional indicators and clinicopathological parameters in predicting the progression and prognosis for pathological stage II-III rectal cancer (RC) patients without neoadjuvant radiotherapy. In addition, we sought to explore the high-risk population who may require postoperative chemotherapy. METHODS: A total of 894 consecutive RC patients were enrolled in this study. Univariate and multivariate Cox analysis were performed to identify the independent risk factors for PFS and OS. The nomogram and calibration curves were conducted according to multivariable analysis result. Kaplan-Meier survival curves and log-rank tests were performed for different groups. Finally, random survival forest (RSF) model was developed to predict the probability of progression. RESULTS: Our results revealed that CEA level, pathological stage, tumor deposit, and PNI were independently associated with PFS in RC patients. Similarly, the results indicated that CEA level, pathological stage, tumor deposit, PNI, and NRI were independently associated with OS. RSF model revealed that group 1 had the highest risk of progression at the 12th month of follow-up, group 2 had the highest risk of progression at the 15th month of follow-up, while group 3 had the highest risk of progression at the 9th month of follow-up. Besides, subgroup analysis suggested that the high-risk group needs postoperative adjuvant chemotherapy, while patients in the low- and moderate-risk groups may not need postoperative adjuvant chemotherapy. Finally, we validated our results with the SEER database. CONCLUSIONS: In conclusion, we demonstrated that preoperative nutritional indicator and clinicopathological parameters could act as auxiliary prognostication tools for RC patients without neoadjuvant radiotherapy. We also established follow-up strategies for different groups of patients. Collectively, incorporating nutritional assessment into risk stratification for RC resection is crucial and should be an integral part of preoperative planning.

Intravenous dexamethasone administration during anesthesia induction can improve postoperative nutritional tolerance of patients following elective gastrointestinal surgery: A post-hoc analysis.

Aim: To investigate the effect of intravenous dexamethasone administration on postoperative enteral nutrition tolerance in patients following gastrointestinal surgery. Methods: Based on the previous results of a randomized controlled study to explore whether intravenous administration of dexamethasone recovered gastrointestinal function after gastrointestinal surgery, we used the existing research data from 1 to 5 days post operation in patients with enteral nutrition tolerance and nutrition-related analyses of the changes in serum indices, and further analyzed the factors affecting resistance to enteral nutrition. Result: The average daily enteral caloric intake was significantly higher in patients receiving intravenous administration of dexamethasone during anesthesia induction than in controls (8.80 ± 0.92 kcal/kg/d vs. 8.23 ± 1.13 kcal/kg/d, P = 0.002). Additionally, intravenous administration of 8 mg dexamethasone during anesthesia induction can reduce the changes in postoperative day (POD) 3, POD5, and preoperative values of serological indices, including ΔPA, ΔALB, and ΔRBP (P < 0.05). In the subgroup analysis, dexamethasone significantly increased the average daily enteral nutrition caloric intake in patients undergoing enterotomy (8.98 ± 0.87 vs. 8.37 ± 1.17 kcal/kg/d, P = 0.010) or in female patients (8.94 ± 0.98 vs. 8.10 ± 1.24 kcal/kg/d, P = 0.019). The changes of serological indexes (ΔPA, ΔALB, and ΔRBP) in the dexamethasone group were also significantly different on POD3 and POD5 (P < 0.05). In addition, multivariate analysis showed that dexamethasone use, surgical site, and age might influence enteral nutrition caloric tolerance. Conclusion: Postoperative enteral nutrition tolerance was significantly improved in patients receiving intravenous administration of dexamethasone during anesthesia induction, especially in patients following enterotomy surgery, with significant improvements in average daily enteral caloric intake, PA levels, ALB levels, and RBP levels.

Novel nutritional indicator as predictors among subtypes of lung cancer in diagnosis.

Introduction: Lung cancer is a serious global health concern, and its subtypes are closely linked to lifestyle and dietary habits. Recent research has suggested that malnutrition, over-nutrition, electrolytes, and granulocytes have an effect on the development of cancer. This study investigated the impact of combining patient nutritional indicators, electrolytes, and granulocytes as comprehensive predictors for lung cancer treatment outcomes, and applied a machine learning algorithm to predict lung cancer. Methods: 6,336 blood samples were collected from lung cancer patients classified as lung squamous cell carcinoma (LUSC), lung adenocarcinoma (LUAD), and small cell lung cancer (SCLC). 2,191 healthy individuals were used as controls to compare the differences in nutritional indicators, electrolytes and granulocytes among different subtypes of lung cancer, respectively. Results: Our results demonstrated significant differences between men and women in healthy people and NSCLC, but no significant difference between men and women in SCLC patients. The relationship between indicators is basically that the range of indicators for cancer patients is wider, including healthy population indicators. In the process of predicting lung cancer through nutritional indicators by machine learning, the AUC of the random forest model was as high as 93.5%, with a sensitivity of 75.9% and specificity of 96.5%. Discussion: This study supports the feasibility and accuracy of nutritional indicators in predicting lung cancer through the random forest model. The successful implementation of this novel prediction method could guide clinicians in providing both effective diagnostics and treatment of lung cancers.

Prognostic Value of Controlling Nutritional Status Score in Advanced Hypopharyngeal Cancer.

OBJECTIVE: The purpose of this study was to investigate the prognostic significance of the preoperative controlling nutritional status (CONUT) score in patients with resectable advanced hypopharyngeal cancer. METHODS: This retrospective study included 113 advanced hypopharyngeal cancer patients who underwent curative resection in our hospital from 2013 to 2017. The association between the CONUT score and clinicopathological variables was evaluated. The association between CONUT score and survival was analyzed using Kaplan-Meier survival curves and Cox regression. The efficacy of the CONUT score and other immune-nutritional markers to predict prognosis was compared using a time-dependent receiver operating characteristic (ROC). RESULTS: Patients were divided into the high-CONUT score group (≥3) and the low-CONUT score group (≤2) according to ROC analysis. The CONUT score was associated with body mass index (p = 0.047), monocyte (p = 0.021), pharyngocutaneous fistula (p = 0.045), flap repairment (p = 0.034), tumor (T) classification (p = 0.034), node (N) classification (p = 0.036), subsite of tumor (p = 0.035), and negative pathologic factors (p < 0.001). Tumor, node, metastasis (TNM) stage, negative pathologic factors, adjuvant radiotherapy, postoperative chemoradiotherapy, and CONUT score were independent prognostic factors for survival. Patients with a higher CONUT score had worse overall survival (OS) (hazard ratio: 2.76, 95% confidence interval [CI]: 1.44-5.29, p = 0.002) and disease-free survival (hazard ratio: 2.51, 95% CI: 1.28-4.91, p = 0.007). The area under the curve of the CONUT score (0.799) to predict 5-year OS was greater than those of Preoperative Nutritional Index (0.769), platelet-to-lymphocyte ratio (0.643), neutrophil-to-lymphocyte ratio (0.565), and lymphocyte-to-monocyte ratio (0.577). CONCLUSION: The CONUT score is a prognostic marker for patients with resectable advanced hypopharyngeal cancer. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:2613-2620, 2023.

Precision-based tertiary care improves nutritional status and quality of life in patients undergoing adjuvant chemotherapy after radical gastrectomy for gastric cancer.

OBJECTIVE: To assess the impact of a precision-based tertiary care protocol, including participatory dietary care, on the nutritional status, immune function, and quality of life in gastric cancer patients after radical gastrectomy. METHODS: The clinical and laboratory data of 124 patients diagnosed with gastric cancer at the Second People's Hospital of Lanzhou City from June 2020 to May 2022 were collected and retrospectively analyzed. The patients were grouped into a control group of 54 patients who received standard care and a study group of 70 patients who additionally received detailed tertiary care and bundled nutritional interventions. The clinical data (age, gender, surgical method, clinical staging, chemotherapy regimen, histories of diabetes, hypertension, smoking, alcohol consumption, time to first flatus and bowel movement, time to first liquid intake, length of hospital stay, complications at discharge, PG-SGA score, and QLQ-C30 score) and lab indices (serum albumin (ALB), prealbumin (PA), transferrin (TRF), hemoglobin (Hb), immunoglobulin A (IgA), M (IgM), and G (IgG)) were compared between the two groups. RESULTS: Study group had significantly higher levels of ALB, PA, TRF, Hb, IgA, IgM, and IgG compared to the control group after intervention (all P<0.001). QLQ-C30 score was higher while PG-SGA score was lower in the study group (both P<0.01). Postoperative digestive system recovery was faster in the study group, as evidenced by a shorter time to first anal defecation, bowel movement, liquid food intake, and hospital stay (P<0.001). Complication rate was significantly lower in the study group (P<0.05). Cox regression analysis showed age (P=0.021) and clinical stage (P=0.039) as independent prognostic factors, while treatment regimen was not (P>0.05). CONCLUSION: Precision-based tertiary care protocol can improve nutritional status, enhance immune function, and facilitate faster postoperative recovery for gastric cancer patients following gastrectomy, thus greatly improving the quality of life of the patient. However, age and clinical staging, rather than the care protocol, are independent prognostic factors for patients' 1-year survival.

The reference ranges and characteristics of lymphocyte parameters and the correlation between lymphocyte parameters and routine health indicators in adults from China.

BACKGROUND: Assessment of immune function is of key importance in recognition of disease or healthy status, which still faces challenge in clinical practice. We conducted a 10-center study to investigate lymphocyte parameters including the number, phenotype and IFN-γ-producing ability, and routine laboratory indicators by using the standard method. RESULTS: Although the heterogeneity of lymphocyte parameters was widely found, we have established the normal ranges of these parameters by using pooled data which showed no significant difference among centers. Cluster analysis of 35 parameters found 3 interesting clusters which represented different immunological status. Cluster 1 (parameters: IFN-γ+CD4+ T cell percentage and IFN-γ+CD8+ T cell percentage) represented current lymphocyte function, which was associated with indicators such as body mass index and red blood cell; Cluster 2 (parameters: NK cell number and CD45RA+CD4+ T cell percentage) represented potential of lymphocytes, which was associated with indicators such as albumin and high-density lipoprotein. Cluster 3 (parameters: HLA-DR+CD8+ T cell percentage) represented inflammatory status, which was associated with indicators such as low-density lipoprotein, globulin and age. Correlation analysis found that nutritional indicator albumin is significantly positively correlated with lymphocyte potential. Triglyceride and body mass index were positively correlated with current lymphocyte function rather than lymphocyte potential. The loss of CD8+ T cells was extremely pronounced with increasing age and was one of the most important factors to cause immunosenescence, which may be associated with increased glucose. CONCLUSIONS: We have established the normal ranges of lymphocyte parameters in different areas. This study elucidates the key indicators used to reflect the current function or potential of lymphocytes, which may provide a valuable clue for how to keep immunity healthy.

Controlling Nutritional Status (CONUT) score is a prognostic marker for laryngeal cancer patients with curative resection.

BACKGROUND: To investigate the prognostic value of pre-treatment Controlling Nutritional Status (CONUT) score in laryngeal cancer. METHODS: Preoperative CONUT score was retrospectively calculated in 154 laryngeal cancer patients who underwent curative resection in our hospital from 2013 to 2016. The associations of CONUT with clinicopathological factors and survival were evaluated. The efficacy of CONUT score to predict prognosis was evaluated. RESULTS: The CONUT score was associated with body mass index (p = 0.033), neutrophil (p = 0.011), tumor size (p = 0.017), pTNM stage (p = 0.001), adjuvant radiotherapy (p < 0.001), negative pathologic factors (p < 0.001), and larynx preservation (p < 0.001). Patients with a higher CONUT score had worse overall survival (hazard ratio: 1.94, 95% confidence interval [CI]: 1.13-3.72, p = 0.039) and disease-free survival (hazard ratio: 2.16, 95% CI: 1.19-3.90, p = 0.011). The area under the curve of CONUT score (0.728) was higher than Preoperative Nutritional Index (0.72), platelet-to-lymphocyte ratio (0.675), and neutrophil-to-lymphocyte ratio (0.687). CONCLUSION: The CONUT score can be useful for predicting survival in laryngeal cancer patients after curative resection.

Sustainability Dimensions of the Mediterranean Diet: A Systematic Review of the Indicators Used and Its Results.

The concern about sustainability is growing and the Mediterranean diet has been extensively identified as a promising model, with benefits for human and environmental health. This systematic review aims to identify and describe the indicators that have been used to evaluate the sustainability of the Mediterranean diet and the results from their application. A methodology using PRISMA guidelines was followed, and searches were performed in Web of Science, PubMed, Scopus, and GreenFile. A total of 32 studies assessing the sustainability of the Mediterranean diet were identified. Twenty-five of these studies quantified the environmental impact, 7 studies evaluated the nutritional quality, and 12 studies assessed the daily cost of this dietary pattern. A total of 33 distinct indicators were identified, of which 10 were used to assess the environmental dimension (mainly, carbon, water, and ecological footprint), 8 were used to assess the nutritional dimension (mainly Health score and Nutrient Rich Food Index), 1 was used to assess the economic dimension (dietary cost), and 8 used combined indicators. The remaining 6 indicators for the assessment of sociocultural dimension were only identified in 1 study but were not measured. The Mediterranean diet had a lower environmental impact than Western diets and showed a carbon footprint between 0.9 and 6.88 kg CO2/d per capita, a water footprint between 600 and 5280 m3/d per capita, and an ecological footprint between 2.8 and 53.42 m2/d per capita. With regard to the nutritional dimension, the Mediterranean diet had a high nutritional quality and obtained 122 points on the Health score and ranged between 12.95 and 90.6 points on the Nutrient Rich Food Index. The cost of the Mediterranean diet is similar to other diets and varied between 3.33 and 14.42€/d per capita. These findings show that no uniformity in assessing the MDiet's sustainability exists.

Nursing Practice Based on Evidence-Based Concepts to Prevent Enteral Nutrition Complications for Critically Ill Neurosurgical Patients.

Purpose: To explore the practical value of enteral nutrition care guided by evidence-based concepts in preventing enteral nutritional complications in critically ill neurosurgical patients. Methods: Three hundred critically ill patients from March 2020 to October 2021 from our neurosurgery department were included in the study. Patients were divided into a control group (March to December 2020, n = 150) and a study group (January to October 2021, n = 150) according to the order of their admission. The control group received conventional enteral nutrition care, and the study group received enteral nutrition care based on evidence-based concept guidance. The levels of serum nutritional indicators [hemoglobin (Hb), albumin (ALB), and total protein (TP)], feeding compliance rate, the incidence of complications (gastric retention, bloating, diarrhea, reflux, vomiting, aspiration, stress ulcers, etc.), and prognosis during the observation period were compared between the two groups. The scores of the questionnaire of knowledge, attitude, and practice on nutrition among neurosurgical nurses before and after the implementation of evidence-based care were compared among nursing staff in the study group. Results: At 1 and 2 weeks after enrollment, Hb, ALB, and TP levels were lower in both groups than before enrollment in the same group (P < 0.05). At 2 weeks after enrollment, Hb, ALB, and TP levels were higher in both groups than at 1 week after enrollment in the same group (P < 0.05). At 1 and 2 weeks after enrollment, Hb, ALB, and TP levels were higher in the study group than in the control group (P < 0.05). At 7 days after feeding, the feeding compliance rate was higher in the study group (94.67%) than in the control group (70.00%) (P < 0.05). The total complication rate was lower in the study group (8.00%) than in the control group (16.00%) (P < 0.05). The percentage of good prognosis was higher in the study group (34.00%) than in the control group (23.33%) (P < 0.05). After the implementation of evidence-based care, caregivers in the study group scored higher on nutrition knowledge, nutrition attitudes, and nutrition practices than those before the implementation (P < 0.05). Conclusion: The implementation of evidence-based nursing interventions in critically ill neurosurgical patients based on evidence-based concepts is of great clinical value in correcting their nutritional status, preventing enteral nutritional complications, improving prognosis, and enhancing the nutritional knowledge, attitudes, and practices of nursing staff.

Introduction. L'étude visait évaluer les indicateurs de l'alimentation du nourrisson et du jeune enfant liés à l'état nutritionnel dans la zone de santé de Kapolowe, province du Haut Katanga avant les essais cliniques. Matériel et méthodes. Nous avons conduit une étude descriptive transversale dans la communauté auprès des 568 couples mère-enfant 6-23 mois évalués sur les indicateurs nutritionnels associés à la malnutrition. Résultats. L'allaitement maternel optimal était observé chez 10,7% des couples mère-enfant et l'alimentation complémentaire adéquate bénéficiée par 5,5% des enfants. Presque 25,6% des ménages utilisaient des toilettes améliorées, 98,8% des ménages buvaient l'eau des sources protégées et 12,1% des mères pratiquaient un minimum de lavage de mains. Le premier aliment complémentaire donné à la moitié des enfants (46%) était importé, mais 60,3 % des mères utilisaient le mélange farine de maïs + huile + sucre comme aliment de complément. La prévalence de la malnutrition aiguë, de la malnutrition chronique et de l'insuffisance pondérale était respectivement de 11,9%, 37% et 26,8%. La malnutrition aiguë était associée à l'occupation de la mère, au niveau socio-économique du ménage, à la Religion de la mère, à la consultation prénatale suivie par la mère, au Minimum de Diversité Alimentaire, à l'allaitement maternel non optimal, aux infections récurrentes et au faible poids de naissance. L'insuffisance pondérale était associée au sexe, à l'occupation de la mère, au niveau socio-économique, à la religion de la mère, au minimum de diversité alimentaire, à l'allaitement maternel non optimal, aux infections récurrentes et au faible poids de naissance.

Introduction. The aim of the study was to assess infant and young child feeding indicators related to nutritional status in the Kapolowe health zone, Haut Katanga province prior to the clinical trials. Material and methods. We conducted a descriptive cross-sectional study in the community among568 mother-child pairs 6-23 months of age assessed on nutritional indicators associated with malnutrition. Results. Optimal breastfeeding was observed in 10.7% of the mother-child pairs and adequate complementary feeding in 5.5%. Almost 25.6% of households used improved toilets, 98.8% of households drank water from protected springs and 12.1% of mothers practiced minimal hand washing,12.1% of mothers practiced minimal handwashing. The first supplementary food given to half of the children (46%) was imported food, but 60.3% of mothers used maize flour + oil + sugar as a complementary food. The prevalence of acute malnutrition, chronic malnutrition and under weight were 11.9%, 37% and26.8% respectively. Acute malnutrition was associated with the mother's occupation, household socio-economic level, mother's religion, prenatal consultation attended by the mother, minimum dietary diversity, non-optimal breastfeeding, recurrent infections, and low birth weigh. Underweight was associated with gender, maternal occupation, socio-economic level, maternal religion, minimum dietary diversity, non-optimal breastfeeding, recurrent infections and low birth weight. Chronic malnutrition was associated with gender, socio-economic level, minimum meal frequency, type of toilet used, non-optimal breastfeeding, recurrent infections, and low birth weight. Conclusion. The prevalence of malnutrition, in all its forms, is still very high and worrying among children aged 6-23 months. The feeding practices are predictors of it.

Effect of standardized enteral nutrition on AECOPD patients with respiratory failure.

OBJECTIVE: To investigate the effects of standardized enteral nutrition (EN) on nutritional indicators and immunological functioning of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) patients with respiratory failure. METHODS: We selected 92 cases of AECOPD patients with respiratory failure as the research objects, and classified them into two groups (control/observation group, n=46 respectively) according to random number table. Both groups were given conventional anti-infection and symptomatic treatment. In addition, the control group received diet support therapy, and the observation group was given standard EN treatment. Afterwards, the changes of nutritional indicators, immunological functioning, inflammatory indicators and cardiopulmonary function of the two groups before and after therapy were compared. RESULTS: Hemoglobin (HB), serum albumin (ALB), and total protein (TP) of the two groups after treatment were critically higher than those before treatment, and the indicators in observation group in post-treatment were remarkably higher than those in control group (P<0.05); lymphocyte count (TLC), immunoglobulin A (IgA) and immunoglobulin G (IgG) of the two groups tremendously increased in post-treatment than before receiving treatment, and the post-treatment indicators of observation group were obviously higher than those of control group (P<0.05); high sensitivity C-reactive protein (hs-CRP) and procalcitonin (PCT) in two groups sharply decreased after treatment comparing to which before treatment, and the observation group had notably lower post-treatment indexes than that of the control group (P<0.05); Ejection minutes (LVEF), NT proBNP, partial pressure of carbon dioxide (PaCO2), partial pressure of blood oxygen (PaO2) and pH of the two groups had remarkably improved after treatment, and the improvement effect in observation group was superior to that in control group (P<0.05). CONCLUSION: The standard EN can substantially improve the nutritional status and immunological functioning of AECOPD patients with respiratory failure, reduce the inflammatory indicators, and promote their cardiopulmonary function.

The application of a structural nutritional care management model in severe acute pancreatitis patients undergoing early enteral nutrition via nasal jejunal nutrition tubes.

OBJECTIVE: To investigate the advantages of a structural nutritional care management model (hereafter referred to as structural management) in severe acute pancreatitis (SAP) patients undergoing early enteral nutrition via nasal jejunal nutrition tubes. METHODS: A total of 88 patients with SAP diagnosed and treated in our hospital were recruited as the study cohort and underwent enteral nutrition treatment. A random number table was used for the random grouping. The control group was routinely managed, and the study group was also administered structural management. In the study, we observed and compared the differences and changes in the relevant nutritional indexes (albumin (ALB), prealbumin (PA), and transferrin (TRF)) and the gastrointestinal hormone indexes (gastrin (MTL), vasoactive peptide (VIP), and 5-hydroxytryptamine (5-HT)) before and after the treatment. Between the two groups, we also compared the times required for the recovery of the relevant gastrointestinal physiological function indexes, the mechanical ventilation times, the hospitalization durations in the ICU, the complications, the satisfaction indexes and the satisfaction rates. RESULTS: After the treatment, the relevant nutritional indicators, including ALB (35.26±3.35 g/L), PA (25.19±5.64 g/L), and TRF (2.82±0.54 g/L) in the study group were higher than the ALB (28.19±2.74 g/L), PA (21.29±4.32 g/L), and TRF (2.26±0.32 g/L) in the control group (all P<0.05). After the treatment, the relevant gastrointestinal hormone indicators, including MTL (269.72±37.18 pg/mL) and 5-HT (2214.61±432.95 ng/mL) in the study group were higher than the MTL (231.25±32.63 pg/mL) and 5-HT (1914.26±391.53 ng/mL) in the control group (all P<0.05). Moreover, the VIP in the study group was 53.13±6.17 pg/mL, which was significantly lower than the VIP in the control group (65.29±9.35 pg/mL, P<0.05). The time required for the recovery of the gastrointestinal function indexes in the study group was less than it was in the control group (P<0.05). The duration of the mechanical ventilation (8.16±1.93 days) and the hospitalization durations in the ICU (9.24±0.77 days) in the study group were significantly shorter than the duration of the mechanical ventilation (12.24±1.65 days) and the hospitalization durations in the ICU (13.23±0.88 days) in the control group (all P<0.05). The overall complication rate in the study group was significantly lower than it was in the control group (P<0.05), and the satisfaction rate in the study group was significantly higher than it was in the control group (P<0.05). CONCLUSION: The combined use of structural management in SAP patients undergoing enteral nutrition treatment significantly improved the relevant nutritional indicator and gastrointestinal hormone indicator levels. It also contributed to the recovery of the gastrointestinal function indicators in the SAP patients, reduced the durations of their mechanical ventilation, their hospitalization durations in the ICU, and their complications and contributed to a significant increase in their satisfaction with the nursing.

Body Composition and Selected Nutritional Indicators in Healthy Adults-A Cross-Sectional Study.

BACKGROUND: Body mass composition is subject to constant change and is multifactorially determined. Its analysis in different age groups allows a better understanding of the determinants of the human organism in health and disease. AIM: The study was aimed to conduct cross-sectional assessment of body composition and selected nutritional indicators in healthy adults. METHODS: The cross-sectional study carried out from March 2016 to April 2018 was preceded by a monthly pilot study. All 1333 adults (women 795, 59.6%) aged 20-59 included in the study were from the urban and rural area of the Podkarpackie Province (Poland). These adults were classified into four 10-year age bands. To obtain reliable assessment, selected screening (anthropometry) and in-depth (bioelectrical impedance including phase angle and bioelectrical impedance vector analysis) methods were used. RESULTS: In women, the proportion of individuals affected by overweight and obesity increases significantly with age, with a less pronounced trend in men, as reflected in the observed differences in individual body composition components. A slight (0.45-0.60) correlation was also observed between body mass index (BMI) and percentage of fat mass (FM %) among men with an increasing strength of the association with age, decreasing in the 50-59 years group. In the female group, the correlations described are at a much higher level (0.80 or higher). The described changes in body composition were reflected in body type from athletic to obese, measured by means of the bioelectrical impedance vector analysis (BIVA) method. CONCLUSIONS: Age and gender significantly differentiate body composition of the adult human body. The body composition analysis should be considered as complement screening assessment method, especially as a support for the assessment of nutritional status expressed by BMI.

Nomogram based on nutritional and inflammatory indicators for survival prediction of small cell carcinoma of the esophagus.

OBJECTIVES: Small cell carcinoma of the esophagus (SCCE) is a rare type of esophageal cancer, and the parameters for prediction of SCCE outcome are unclear. This study aimed to construct a nomogram to predict the outcome of SCCE. METHODS: Patients who underwent treatments at the Sun Yat-Sen University Cancer Center were recruited and divided randomly into training and validation cohorts (61 and 32 patients, respectively). A Cox regression analysis was utilized to identify independent prognostic factors to establish a nomogram and predict overall survival (OS) and disease-free survival (DFS). RESULTS: Information on pretreatment nutritional candidate hemoglobin and inflammation-related neutrophil-to-lymphocyte ratio and platelet count were entered into the nomogram. In the training cohort, the concordance index of the nomogram for OS was 0.728, higher than that obtained by tumor/node/metastasis staging (0.614; P = 0.014). A significant difference was observed in the nomogram for DFS (0.668 vs tumor/node/metastasis stage: 0.616; P = 0.014). Similar results were found in the validation group. The decision curve analysis, net reclassification improvement, and integrated discrimination improvement showed moderate improvement of the nomogram in predicting survival. Based on the cut point calculated according to the constructed nomogram, the high-risk group had poorer OS and DFS than the low-risk group in both cohorts (all P < 0.05). Moreover, the DFS of patients receiving surgery in the high-risk group was better than that of patients receiving single radiation therapy or chemotherapy (P = 0.0111). CONCLUSIONS: A nomogram based on nutrition- and inflammation-related indicators was developed to predict the survival of patients with SCCE.

The Relationship between Selected Body Composition Components and Cardiopulmonary Resuscitation Parameters in Nurses: An Observational Simulation Study.

The provision of cardiopulmonary resuscitation (CPR) may be related to the physical parameters of the medical personnel, including fat mass (FM) and fat-free mass (FFM) components. In this study, we aimed to assess the relationship between selected body composition components and chest compression and ventilation parameters provided by medical staff. An observational simulation study was undertaken between December 2017 and January 2019 at the Center for Innovative Research in Medical and Natural Sciences of Rzeszów. In all participants (505 nurses, 37.71 y ± 12.16), the body weight and height were measured and the body mass index (BMI) was calculated. The body composition indicators were obtained using a bioelectrical impedance device, AKERN BIA 101. Afterwards, all participants performed CPR sequences (30 chest compressions and rescue for 2 breaths) for 2 min on a Laerdal Resusci Anne simulator placed on an examination couch with a self-inflating bag and a face mask. Our observations proved that high values of the anthropometric, nutritional and body composition parameters of the medical staff demonstrated a positive significant correlation with the depth and rate chest parameters and were inversely related to the chest adequate recoil. No statistically significant differences were found between the FM or FFM components and ventilation parameters. This study showed that nutritional status and body composition components may be important factors affecting the quality of CPR.

The complexity of co-limitation: nutrigenomics reveal non-additive interactions of calcium and phosphorus on gene expression in Daphnia pulex.

Many lakes across Canada and northern Europe have experienced declines in ambient phosphorus (P) and calcium (Ca) supply for over 20 years. While these declines might create or exacerbate nutrient limitation in aquatic food webs, our ability to detect and quantify different types of nutrient stress on zooplankton remains rudimentary. Here, we used growth bioassay experiments and whole transcriptome RNAseq, collectively nutrigenomics, to examine the nutritional phenotypes produced by low supplies of P and Ca separately and together in the freshwater zooplankter Daphnia pulex. We found that daphniids in all three nutrient-deficient categories grew slower and differed in their elemental composition. Our RNAseq results show distinct responses in singly limited treatments (Ca or P) and largely a mix of these responses in animals under low Ca and P conditions. Deeper investigation of effect magnitude and gene functional annotations reveals this patchwork of responses to cumulatively represent a co-limited nutritional phenotype. Linear discriminant analysis identified a significant separation between nutritional treatments based upon gene expression patterns with the expression patterns of just five genes needed to predict animal nutritional status with 99% accuracy. These data reveal how nutritional phenotypes are altered by individual and co-limitation of two highly important nutritional elements (Ca and P) and provide evidence that aquatic consumers can respond to limitation by more than one nutrient at a time by differentially altering their metabolism. This use of nutrigenomics demonstrates its potential to address many of the inherent complexities in studying interactions between multiple nutritional stressors in ecology and beyond.

Intestinal Bacteroides sp. Imbalance Associated With the Occurrence of Childhood Undernutrition in China.

Undernutrition (UN) is a worldwide concern affecting morbidity and mortality among children, but the safety and long-term efficacy of its current treatments remain controversial. Recent evidence showing the roles of the gut microbiome (GM) in nutrient absorption indicates its usefulness in alternative interventions to treat UN safely with sustainable amelioration. To enhance our understanding of the GM and childhood undernutrition, we deep sequenced the gut metagenomes of 65 children with moderate or severe undernutrition (UN group) and 61 healthy children (HC group) to identify associated taxa and genes using a two-stage validation scheme. At stage I, 54 UN patients and 51 healthy children were enrolled for the discovery of GM markers in UN children. The accuracy of the markers was then tested in an additional 11 UN patients and 10 healthy children at stage II. Compared to the HC group, the UN group had lower richness in microbial genes (P = 0.005, FDR = 0.005) and species (P = 0.002, FDR = 0.002). The distributions of bacterial genes enable the identification of 16 gene markers with which to discriminate UN patients with high accuracy [averaged areas under the receiver operating curve (AUC) = 0.87], including three Bacteroides uniformis genes that are responsible for the synthesis of iron transporters. We also identified four species markers that enable the UN patients to be confidently discriminated from the HC children (averaged AUC = 0.91), namely Bacteroides ovatus, Bacteroides uniformis, Bacteroides uniformis, and Bacteroides vulgatus. In addition, metabolic comparison showed significantly decreased isobutyric acid (P = 0.005, FDR = 0.017) and increased isovaleric acid (P = 0.006, FDR = 0.017) in UN patients. We also identified notable correlations between microbial species and short-chain fatty acids (SCFAs) and several nutritional indicators, including acetic acid and iron (r = 0.436, P = 0.029), butyric acid and iron (r = 0.422, P = 0.036), butyric acid and lymphocyte (r = -0.309, P = 0.011), and acetic acid and total protein (r = -0.303, P = 0.043). Taken together, the distinct features of gut microbiota in UN patients highlight the taxonomic and functional shift during the development of UN and provide a solid theoretical basis for intervention in childhood undernutrition through gut microbes.
